Timestamp attributes now supported in Vercel Flags
Vercel Flags now supports timestamp attributes for entities, allowing you to create time-based targeting rules. Use this feature to run limited-time campaigns, show content between specific dates, or target users based on registration date.
now supports timestamp attributes for , which represent the users, teams, devices, or requests evaluated by a flag.Vercel Flagsentities
Use timestamp attributes to show a campaign page only between two dates, run a Black Friday promotion, or target users who registered before a cutoff.
You can configure timestamp attributes in the dashboard or via the CLI.
In the Vercel dashboard, open , select , and create or select an entity. Add an attribute and set its data type to .FlagsEntitiestimestamp
Or define the attribute with the CLI:
Whether you configure the attribute in the dashboard or CLI, your application must provide its value when evaluating a flag. The entity and attribute names must match your configuration, and the value must be a Unix epoch timestamp in milliseconds.
This Flags SDK example passes the current time as . returns the required value in milliseconds. Keeping it inside ensures that every flag evaluated during the same request uses the same time:system.timeDate.now()dedupe()
In the dashboard, open the flag and add a targeting rule using the timestamp attribute. The rule compares the value from your application with a date and time you choose.
Rules support , , , and . The date and time picker uses your local timezone.is afteris at or afteris beforeis at or before
